I think most people will probably say to take them straight to the vet. For me, it depends on the dog's size, the type of chocolate that was consumed, how much chocolate was eaten, and how the dog is acting. If the dog is acting sick or unusual, I'll always head to the vet. If the dog ate a lot of dark chocolate or the kind of chocolate you bake with, I'll head to the vet. But if the dog is acting normally and it was whipped chocolate, white chocolate, or a chocolate bar that's filled with peanut butter, then I'm going to take the watch and wait approach. Of course, I'll head to the vet if anything changes.
